Abstract
PURPOSE: To obtain the ion exchange body cellulose solid spherical particles of superior chemical and physical properties and separating capacity by introducing ion exchange groups to the cellulose solid particles produced then swelling these by an alkali thereby cross-linking the same.
CONSTITUTION: First, the cellulose solid spherical particles are produced by such a method as inliquid drying method. Next, exchange groups such as diethyl amino ethyl and sulfa propyl are introduced to these cellulose particles, after which they are suspended to swell in an alkali solution such as caustic soda while neutral salt such as sodium chloride is being added. Thereafter, they are treated with cross-linking agents such as epichlorohydrin and formaldehyde. In this way, the cellulosic ion exchange body solid spherical particles which are physically and chemically stable and vary in exclusive limit molecular weight are obtained.
